AGE OF BEDS CONTAINING THE CORALS. 17 



says: "This, like the Eocene of North CaroHna, is regarded by Harris as 

 newer than that of Maryland and Virginia, which has been included under 

 the name of Pamunkey by Darton." One specimen of a species of Endo- 

 pachys was found in the material belonging- to the Academy of Natural 

 Sciences of Philadelphia. In no other State is a species of this genus 

 known from a horizon below the Claibornian; thei-efore I am inclined to 

 Harris's opinion that the Shark River beds are higlier than the Aquia 

 Creek beds of Darton's Pamunkey formation. 



Maryland and Virginia. — In a rcccnt paper^ Prof G. D. Harris has advanced 

 the opinion that the Eocene of tliese States, the Pamunkey of Darton,- rep- 

 resents the same horizon as the Bells Landing beds of Alabama. Prof. 

 W. B. Clark ^ has more recently published the opinion that the Maryland 

 and Vu'ginia Eocene deposits "represent the greater portion of the Eocene 

 series of the Grulf, its highest members alone excepted." * The corals 

 which have been collected and studied from this regiciu all belong to the 

 same horizon. There is only one species, Eupsammia elahorata (Conrad), 

 common to the Alabama region, where it is confined to the Bells Landing 

 and Woods Bluff beds. Since the above was written Professor Clark has 

 sent me some specimens of BalanophyUia desinophyUum 3I.-Edw. and H. from 

 1 mile southeast of Mason Sj^rings, Maryland. This species ranges from 

 the Bells (Greggs) Landing horizon into the Lower Claiborne. 



South Carolina and Georgia. — Thc collectious froiu tlicsc Statcs are insiguificant, 

 and sufficient careful paleontologic and stratigraphic work has not been 

 done to make a discussion of the Eocene in them possible. 



Alabama, Mississippi, Arkansas, and Louis ana. ThcSC StateS fumisll the typC SeCtioU 



of the Gulf States Eocene, and practically every horizon of both the Eocene 

 and Lower Oligocene contains species of fossil corals. The Gulf States 

 section in the table of formations is sufficient explanation of the stratigraphic 

 terms. 



Texas. — Mr. E. T. Dumble, in the Journal of Geology for September, 

 1894, summarized what is known concerning the general character and the 

 sequence of the Eocene beds of Texas.
